Abstract
Description
Technical Field
[0001] This utility model relates to the field of berry harvesting and collection technology, and in particular to a buffer-type collection device for berry harvesting. Background Technology
[0002] A berry is a soft, juicy, fleshy fruit that develops from the ovary or other floral organs. It is characterized by a thin exocarp, pulpy flesh with high water content, and small, numerous seeds scattered throughout the pulp. The general developmental steps of a berry are as follows: first, a single or multiple carpels fused together to form a pistil, and then the fruit develops from the superior or inferior ovary.
[0003] In berry harvesting, existing harvesting methods have significant efficiency bottlenecks and occupational health hazards. Taking mulberries and other high-branch berries as an example, workers mostly use the traditional harvesting mode of holding a basket or carrying a basket on their back. The weight of the basket directly affects the shoulders and back of the human body. Continuous work can easily cause muscle strain, and the shift in the center of gravity increases the risk of falling. Carrying the basket requires one hand to support it continuously to maintain balance, which leads to overuse of one side of the body and reduces the coordination of picking movements. Although the vibration harvesting method can make the fruit fall off by vibrating the tree trunk, the cell wall rupture caused by the free fall impacting the ground seriously affects the commercial value.

[0006] According to the present invention, a buffer-type collection device for berry harvesting is provided, wherein the screening box is provided with a buffer frame and a screen, the buffer frame includes a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the screening box, a sleeve roller is sleeved on the outer side of the rotating shaft, and multiple fan blades are equidistantly installed on the outer side wall of the sleeve roller; the screen is installed obliquely inside the screening box, and the screen is located above the collection mechanism.
[0007] According to the present invention, a buffer-type collection device for berry harvesting is provided, wherein a storage groove is provided on the outer side of the bottom of the screening box, and the storage mechanism includes a storage box and a side plate fixed to one side thereon. The storage box passes through the storage groove and extends into its inner cavity, and the side plate abuts against the outer wall of the screening box.
[0008] According to the present invention, a buffer-type collection device for berry harvesting is provided, wherein the collection box is provided with a collection trough, and a partition plate is installed in the collection trough to divide the trough into two collection chambers.
[0009] According to the present invention, a buffer-type collecting device for berry harvesting is provided, wherein the fan blade has an L-shaped structure and its outer side is covered with a first buffer plate made of rubber.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0032] This utility model provides a buffer-type collection device for berry harvesting. See [link to relevant documentation]. Figures 1-4 The system includes: a screening box 100 for screening small berries; a storage mechanism 200, detachably installed inside the screening box 100 for holding the screened small berries; and a fruit receiving mechanism 300, installed on top of the screening box 100 for conveying the small berries into the screening box 100. The screening box 100 is equipped with a buffer frame 310 and a screen 120. The buffer frame 310 includes a rotating shaft 111, which is rotatably connected to the inner wall of the screening box 100. A roller 112 is sleeved on the outer side of the rotating shaft 111, and multiple fan blades 113 are equidistantly installed on the outer side wall of the roller 112. The screen 120 is installed obliquely inside the screening box 100, and is positioned above the storage mechanism 200.
[0033] After the harvested berries are slid into the screening box 100 through the fruit receiving mechanism 300, they first fall onto the surface of the fan blades 113. The weight of the berries drives the rotating shaft 111 below the fan blades 113 to rotate, causing the four sets of equidistant fan blades 113 to move in a cycle, forming a dynamic receiving surface. The periodic rotation of the fan blades 113 achieves a dispersed and buffered fall of the berries, while avoiding crushing damage caused by accumulation. After being buffered by the fan blades 113, the berries fall onto the top of the screen 120. Small-diameter berries fall directly into the collection mechanism 200 through the screen holes during the rolling process, while large-diameter berries roll along the inclined surface of the screen 120 into the other side of the collection mechanism 200.
[0034] For example, the number of fan blades 113 is 4-8 sets and they are evenly distributed along the circumference of the sleeve roller 112.
[0035] In one embodiment, a storage groove 130 is provided on the outer side of the bottom of the screening box 100. The storage mechanism 200 includes a storage box 210 and a side plate 220 fixed to one side thereon. The storage box 210 passes through the storage groove 130 and extends into its inner cavity. The side plate 220 abuts against the outer wall of the screening box 100. A collection groove is provided inside the storage box 210, and a partition plate 211 is installed inside the collection groove to divide the groove into two collection chambers.
[0036] The storage mechanism 200 is connected to the screening box 100 via a sliding rail through the storage groove 130. Before screening, the storage box 210 is pushed into the storage groove 130 along the sliding rail, so that the storage mechanism 200 is completely embedded inside the screening box 100. Small-diameter berries fall directly into the first collection chamber of the storage box 210 through the sieve holes, while large-diameter berries roll into the second collection chamber along the inclined surface of the screen 120.
[0037] The partition plate 211 is used to physically isolate the two cavities. The partition plate 211 uses a food-grade silicone sealing strip to physically isolate the fruit while avoiding collision damage.
[0038] In one embodiment, the fan blade 113 has an L-shaped structure, and its outer side is covered with a first buffer plate 114 made of rubber.
[0039] By utilizing the shape of the fan blade 113L, the berries can be intercepted, preventing them from slipping off one side of the first buffer plate 114. When the berries fall from the buffer frame 310, they impact the first buffer plate 114 at the top of the fan blade 113. This buffer plate is made of multi-layer composite rubber material, which absorbs the kinetic energy of the falling berries through material deformation. The surface of the first buffer plate 114 is designed as a micro-arc guide surface, allowing the berries to slide along the tangential direction after contact, ensuring that the berries are not damaged during the fall.
[0040] In one embodiment, the receiving mechanism 300 includes a buffer frame 310 and a funnel 320. The buffer frame 310 is installed at an angle on the top of the screening box 100, and the funnel 320 is installed at the top of the buffer frame 310. The inclination angle of the buffer frame 310 is 30°-60°.
[0041] Workers feed the harvested berries into the inclined buffer rack 310 through the funnel 320. The inclined design of the pipe allows the berries to slide down the slope, reducing the vertical impact force by extending the falling path and avoiding direct impact damage.
[0042] In one embodiment, a plurality of second buffer plates 311 perpendicular to the horizontal plane are rotatably connected inside the buffer frame 310, and each second buffer plate 311 is set at an angle to the inner wall of the buffer frame 310.
[0043] Berries enter the inclined buffer rack 310 through the funnel 320 and roll naturally along the inner wall of the pipe. Multiple sets of second buffer plates 311 are vertically installed inside the pipe. The second buffer plates 311 are perpendicular to the inside of the buffer rack 310 and are distributed at intervals along the length of the pipe to form a stepped buffer structure. When the berries roll down, they hit the first second buffer plate 311. The impact force drives the second buffer plate 311 to rotate. After the berries slide away from the first second buffer plate 311, they hit the next level of second buffer plate 311 at a controlled speed. Each level of second buffer plate 311 repeats the above-mentioned rotation buffer process.
[0044] In one embodiment, the impact-facing surface of the second buffer plate 311 is fixed with anti-collision cotton.
[0045] As the berries roll down the buffer rack 310, they strike multiple second buffer plates 311 in sequence. The second buffer plates 311 are equipped with anti-collision cotton, which is made of open-cell polyurethane foam material to absorb impact energy.
[0046] In one embodiment, the mesh diameter of the screen 120 is 5-15 mm, and its tilt angle is 10°-30°.
[0047] In one embodiment, the two ends of the rotating shaft 111 are rotatably connected to the side wall of the screening box 100 via bearings.
[0048] In one embodiment, the funnel 320 has a flexible flared edge at its opening, and a cushioning sponge layer is attached to its inner wall.
[0049] In one embodiment, the bottom of the screening box 100 is provided with an adjustable height support leg. The support leg includes a threaded rod and a sleeve. The top end of the threaded rod is fixed to the bottom surface of the screening box 100, and the sleeve is threadedly engaged with the threaded rod and has an anti-slip pad at the bottom.
[0050] The specific usage is as follows: Before screening, the operator pushes the collection box 210 into the collection slot 130 along the slide rail, so that the collection mechanism 200 is completely embedded inside the screening box 100. During operation, the operator puts the harvested berries into the inclined buffer frame 310 through the funnel 320. When the berries roll down, they hit the first second buffer plate 311. The impact force drives the second buffer plate 311 to rotate, completing the initial buffering. After the berries slide off the first second buffer plate 311, they hit the next second buffer plate 311 at a controlled speed. Each second buffer plate 311 repeats the above rotational buffering process. Afterwards, the berries slide into the screening box 100 and fall onto the surface of the fan blades 113, impacting the first buffer plate 114 at the top of the fan blades 113. The weight of the berries drives the rotating shaft 111 below the fan blades 113 to rotate, causing the four sets of equidistant fan blades 113 to move in a cycle, forming a dynamic receiving surface. This avoids crushing damage caused by accumulation. After being buffered by the fan blades 113, the berries fall onto the top of the screen 120. Small-diameter berries fall directly into the first collection chamber of the collection mechanism 200 through the screen holes during the rolling process, while large-diameter berries roll along the inclined surface of the screen 120 into the second collection chamber, completing the screening and collection work.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
